Sumire

Sumire Hikami (氷上 スミレ) commonly referred to as simply Sumire, is a Vocoloid that has currently only been released in Japanese. Her voice is provided by the Japanese signer and idol Mona Tomoyama.

Concept
Data Cardass Aikatsu!'s creative team was looking over songs to release in the 2nd Part of their 2016 series, when they noticed a pattern. Sumire Hikami often had a robotic tone to her voice. So, as an extension to their collaboration with Miku Hatsune and Vocaloid in general, they decided to release Sumire as a limited edition vocaloid.

Etymology
Hikami (氷上) Hi (氷 kouri) means ice and combined with Kami (上 jou) which means top, Hikami means on ice, referencing her mysterious and slightly cold personality.

Sumire (スミレ) is the Japanese word for the violet flower. This may be a reference to her hair color as well as her dainty appearance.

Appearance
Sumire has long periwinkle hair styled in a hime cut that reaches halfway down her back. Her eyes fade in a gradient like style. from blue-violet to a vivid violet. Her skin is also quite pale, and she is slightly taller than normal for her age.

In most appearances, she is seen wearing a light blue checkered top, as well as a skirt in a slightly lighter shade of blue with the same checkered pattern in some places, and white boots with blue and gold accents.

Songs
Her songs often have an eerie vibe to them, but not to the point of being gothic rock. Sumire only has 4 songs by her, most likely due to the fact that she is simply a collaboration vocaloid.
